Print to Tape randomly Drops DV deck out of Record mode.(Update)

craftech wrote on 11/8/2002, 11:10 PM
When "printing to tape" from the timeline via firewire from the ADS Pyro card to a new DV deck (Sony WV-DR9 Japanese import model), the deck stops recording. It is happens at various times..23 minutes, 47 minutes, etc.

To narrow it down:

1. I connected the deck to an analog VHS recorder via the decks analog outputs and the transcoded VHS copy comes out perfectly. The monitor was connected to the VHS deck's analog outs. There is no visible audio or video interruption on the VHS copy at the point where the DV deck stops recording.

2. I have recorded with the deck through its analog inputs to DV and it records without a problem.

3. I also tried using a 4 Pin to 4 Pin firewire cable to record directly from my camera to the deck. I copied an 83 minute tape and a 30 minute tape to a large DV tape in the deck and it didn't fall out of Record mode once.

4. I tried a different IEEE 1394 6 Pin to 4 Pin cable from the card to the deck and the same problem occurs. The deck stops recording Digital Video after a period of time.

5. I posted on the ADS group, but go no response. I have been editing with VV3 for about 8 months now and it is the first time I have run into Print to Tape issues. I have been Printing to Tape to my camera (VX2000)via firewire or through the camera to my analog VHS dubbing rack without a problem. The purpose of the deck was to be able to master longer videos on large DV tapes.

6. I havent tried a different edited video project yet. Could timecode interruptions be an issue?
7. Could the prerendered AVI files be corrupted without there being any visual or audible artifacts on the monitor?

8. Could one of the settings in VV be wrong?


Thanks in advance.

Hi John,

Have you tried "manual" PTT, by disabling the device control? That would mean you press record on the deck, rather than letting Vegas control thr transport.

Is there a menu setting in the deck like "commander" or such that might interfere?

Thanks for the reply,
Yes, that is how I always use it. Manual.

Hi John,

Have you tried PTT from Vegas capture (Full render needed.)? Might help.

Have you tried PTT *using* device control, rather than manual? Might help.


Can you capture using Vegas uninterrupted? Might be a clue...

Is your ethernet networking disabled, IEEE 1394 networking disabled? Might help.

I'll try from VidCapture PTT next. Kind of a nuisance having to render first, but worth a try.

I can't use device control. It appears grayed-out....disabled. I can only use manual device control. Any ideas why?

There are absolutly no visible anomalies on the VHS tape (recorded via pass through on the deck) at the point at which the deck stops recording. There are no obvious audio interruptions either.

The deck works fine when camera firewire to deck firewire is used to copy a miniDV tape in the camera to the DV tape in the deck.
Problem only occurs from the computer firewire output to the deck's firewire input.

Do you know of a firewire expert at this site or another site with whom I can discuss this? Someone who would know the internal electronics of DV decks. I don't know if it's possible for a DV deck to pose a problem from a computer DV signal, yet not directly from a camera tape's DV signal. I would think SOMETHING would be visible at the point at which the deck stops recording.

Thanks Marty......I appreciate the help on this!

Hi John,

The best bleeding-edge folks I consort with are here and on the COW.

My understanding is that there is often a zone between OHCI compatible and OHCI compliant. So, not all decks/cams talk to all software and vice versa.

Are you using the MSDV driver? Some drivers (like the TI driver) are not always happy or helpful.

Yes, I am using the Windows driver...the most current one.

The deck is a popular import here in the states. I returned the first one because it was dropping frames(transport problem), but it dropped frames from any source. I don't believe anything has changed except that I added Ulead DVD Movie Factory to Drive C and SF e-mailed some updated Mpeg2 Main Concept drivers to me which I installed.

Maybe SF has some ideas regarding this thread?

Thanks,

John

If you can print to a camera without problems but have dropouts when recording to a deck...it sounds like the deck. Anything in the deck manual about this? Maybe some different record modes you could try?

I get manual only if I don't have a tape in the deck at that point. I get device control if a tape is in the deck at the time I start PTT.

When recording 1394 from camera to deck......deck records perfectly. 1394 from computer to deck....deck drops out of record mode. Deck manual is in Japanese, vendor provided translation, but as with all Sony products, troubleshooting information is limited. Deck model WV-DR9.

Based upon the fact that DV camera to deck via firewire record fine, analog to DV records fine, and only firewire out from computer to deck causes deck to drop out of Record mode, vendor says it's the computer or the software and not the deck.

I don't have another computer setup to try it with. The one I use for editing is strictly set up for editing only to "avoid problems". I tend to think it's the deck too, but I am going to have to be pretty convincing in order to return it and it will be the SECOND one. Cost me $120 to ship it each time.

I can't get device control for PTT under any circumstances, yet I can get it for video capture and it works well with my VX2000.

*****I have been experimenting with another timeline project and this time I noticed that the deck stopped recording during a FADE. I tried it a second time and it stopped recording in the exact same spot. I guess this is progress.******

Any ideas as to why?

Thanks again,

John

Hi John,

Will it stop 10 times out of 10, same place?

Will it PTT an uninterrupted clip?

Is the fade pre-rendered to a video drive? Might be a burp if the prerenders are on another drive (or especially the system drive)?

Yes, it seems to.

It is prerendered to a separate video drive.

Thanks Marty,

Hi John,

Couple of thoughts:

How bout the prerenders on the same drive?

Can you PTT a sequence of cuts?

Can you PTT a sequence of generated backgrounds or stills?

PTT from Vegas Capture OK?

Marty,

I'll try all that and get back to you.

Hi John,

Another thought, based on a thread over at the COW...

Is there anything in the video like a bright flash, or special effect that the deck might interpret as copy-guard?


You might check that path too.
